How to use Generate Random TSV
- 1. Set rows and columns. Enter Rows and Columns to size the generated table, from a small sample to a larger dataset for testing import performance.
- 2. Decide whether to include a header row. Turn on Include header row to add labeled column names at the top, useful when the tool you are testing expects a header before the data rows.
- 3. Copy the generated TSV. Copy the tab-separated values from the output pane and paste them into a spreadsheet, a database import test, or a script that expects TSV input.
When to use Generate Random TSV
Generate Random TSV produces tab-separated value data at a size you specify, with an optional header row, useful whenever you need sample tabular data without exporting it from a real spreadsheet.
- Testing a TSV import script. You wrote a script that parses tab-separated data into database rows and want generated sample data, both with and without a header row, to confirm the parser handles each case.
- Populating a spreadsheet paste test. You are checking how a web app handles a user pasting tabular data from a spreadsheet, and generating TSV at various row and column counts gives you quick test input.
- Filling a data pipeline test fixture. A data pipeline expects tab-separated input at a certain shape. Generating sample rows and columns confirms the pipeline correctly parses and processes the fields.
- Comparing TSV and CSV parsing behavior. You are testing that your data importer correctly distinguishes tab delimiters from commas, so generating TSV samples alongside CSV samples helps confirm the parser reads each format correctly.
Examples
Three rows, two columns with a header
Output
column1 column2 amber 42 cedar 7
About the Generate Random TSV tool
Generate Random TSV is a free online tool that works entirely inside your web browser. Quickly generate random TSV files. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 120 Random utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 3 settings, including Rows, Columns and Include header row, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
